Be i known that I, CHARLES A. VSrun'rn- "TMNT,l a citizen ofthe United States, and

residentof Plainiield, in thecounty of. Union and `State of New Jersey, have invented a new and useful lImproven'ient in Turbine- Engines, of which the'following is aspecificatlon. f This invent'on 'relates to a turbine engine fand 'has 'as its object to producev an engine of thiseharacter which is very simple, durable and compact inconstruction and which yields themaximni amount'of power in pro- Pulido@ t the amount of pressure medlurn' Wh'lh 1S-eXpended;-' Y

Eachofthe sta- Wtionaryblades is preferably constructed in VI'the form'of a ratchet tooth the front side of' l 'which 'faces'the concaveiside of the outer j blades while the inclined rear side thereof faces the convex side of the outer blades.

the steam supplied through the-conduit d issues from 'the portfe thereof it passes through the (particular inletf, lregistering "therewith'an `into thescorresponding steam *cliamben thence through the nozzle of this chamberand then.issuestangentially from .the loutlet."-thereof. )Thef reaction of the 6 5' stea`in"*upon thus .issuing from ythe outlet-lof causing steam in like manner to 1pass through 'latter to be turned in a direction opposite to .b ades or Aitself and esca es through the saine. W represents a circular'row-of stationary' in the chambepoperates the steam chamber causes the' reaction wheel to turn in the direction of lthe arrow sothat the inlet of the next steam chamber ltsfbrought into registerwith the supply port om the outthe same and issue tangentially This action is repeated as the let thereof.

inlets of the `several steam chambers are brought successively into register with the supply port.-

As the steam issues from the outlets of the several steam chambers of the reaction wheel the saine impinges against the inner row of blades of the impulse wheel and causes the thatl of the reaction 'wheel owing to the 1inpact or iinpelling force of the steam against the inner blades. The curvature of the inner blades causes the steani upon striking the same to be deflected and rebound outwardly at an angle so as to strike the concave side's of the intermediate blades. The steam is now again deflected outwardly at a reverse angle by the intermediate blades and by its reaction against the latter assists the initial steam jets issuing from the nozzles' to turn the reaction wheel as before described. Upon leaving the intermediate blades the steam strikes the concave sides of the outer blades and thereby aids in turning the iin- 95 pulse wheel in a direction opposite the actionwheel. As the steam strikes the outer blades the same is deflected outwardly and in a reverse direction s0 that it impinges a ains't the abrupt faces of the stationary 100 guides from which it reacts and assists the impulse wheel in itsrotary movement. As each outer blade arrives .opposite the4 exhaust the pressure medium has spent Within the ore of the ring B and in front vof the exhaust a relief chamberWlfis formed which ermits freeventof the spent steam from t e outer rotatable, blades to theexhaust, while on the rear side of the exhaust '/wf which prevents the steam from backing up and escaping directly to the `exhaust before it has expended its force.

y l .A While thesteani chambers are in coniniunication with the su ply conduit the steam issuing from the out et thereof actsy directly and at high pressure ja aiiist the blades but when the steam cham ers during the forward movement of the impulse .wheel are cut of fromtlie live steam sup ly then the steam liy expansion and ,at low pressure-against the blades. The supply ort shown` in the drawings is of such widtl that it'lis capable of communicating at one time withf one steam chamber and atv another time with two' of said chambers so that livev .steam is being supplied at all timos to eitlliergne or two of the chambers which 13o 93eme operates directly;againsathe-blades While-the f supply port -e answers' thev steam is.'operatingiexpansively on the blades in the remaining four :chambers 4which* for the time, being are cut off from thesteam.
